Hello All.
I went out and bought a cheap wet/dry grinder. the brand is Pit Bull. (its was at a second hand shop.) It looks decent,The price is well with in my spending limit.
The only question is on the wet stone side of the machine. (its a 8″ wheel 1 1/2″ wide, Rpm is 180 .) the question is can I use oil as a lubricant?
the wheel is new.It is also manmade. grit? but pretty smooth.
It is going into my garage/shop. its not heated when Im not in working in it. I fear water will crack the wheel if left in the cold. (In Mich. the temps can go way below freezing. And that’s in the summer! 😉 . )
I’ve checked out the web site of pit bull. No help there!
there is no manual.
I don’t think a light oil will hurt the stone? are there any thought? pro’s or con’s?

Put a card board box lined with styrofoam over the grinder. Put a 25 watt bulb inside, make sure the bulb does not get anywhere near the styrofoam. This will keep the water from freezing.
Another option would be antifreeze, I have no idea if this is feasable though. It will keep the water from freezing, but might not be suitable for the stone. The stone will soak up a lot of water, you probably have to refill the pond at least once each week.

Hello Mike
thank you for your thoughts.
one question. what would be the difference between anti-freeze and oil?

I would not use oil on a grinding wheel, clogs the pores. Save the oil for oil stones.Besides ,oil gets thick in cold weather. The stone's manufacturer may be able to tell you if antifreeze is acceptable for your stone.

Chris: My Tormek instruction book said to definitely look out for freezing, it will crack the stone. The good news is that they dry out fast and if really dry cold shouldn't hurt it. KDM

Alcohol works fairly well as an anti-freeze and won't gum up the stone.
